[Urbanization, poverty and health in Columbia]

A rapid process of urbanisation is recognisable all over the world today. Already 80% of the world's big cities are located in underdeveloped countries. 60% of their city inhabitants are slum-dwellers living under more or less miserable conditions in shanty towns. This paper documents the reality of life of a 60,000-inhabitants shanty town population in Columbia as well as the implications on health by poverty-linked social environment. In addition to disastrous conditions of housing and nutrition, chronic individual and collective psychological stress seem to be the most important risk factors for the health of the population. The international linkups between wealth, poverty and poverty-conditioned disease make it necessary that physicians of industrial nations also become aware of the world's disparity and injustice in order to help in overcoming miserable living conditions by thinking in global terms.
